Instead of assuming a form of gravity and demand cosmology fit with ΛCDM, a potentially `viable' f(R) gravity model is derived assuming an alternative model of cosmology. Taking the `designer' approach to f(R), a new class of solutions are derived starting with linear coasting cosmology in which scale factor linearly increases with time during matter domination. The derived forms of f(R) are presented as result.
